The Power Plus 520 Nozzle is the best middle of the road upgrade for most MK4 ALH TDIs.

The Fratelli Bosio Power Plus philosophy removes these artificial OEM limitations, by applying industry-leading technology to decades of injector nozzle manufacturing know-how. Each Power Plus nozzle embodies thousands of hours of testing to achieve the most effective design, without compromise.
